Nucleic acid extractor

Abstract

The invention relates to the technical field of medical equipment and particularly relates to a nucleic acid extractor. The nucleic acid extractor comprises a shell, a rack, a nucleic acid extracting module, a sample bin, a reagent region, a multi-pipette module and a single-pipette module, wherein a table board is arranged on the rack; the nucleic acid extracting module, the sample bin and the reagent region are arranged on the table board; the multi-pipette module and the single-pipette module are positioned above the table board; an X arm is arranged on the rack; a multi-pipette Y arm and a single-pipette Y arm are arranged on the X arm; the multi-pipette Y arm and the single-pipette Y arm slide along the X arm; the multi-pipette module is arranged on the multi-pipette Y arm and slides along the multi-pipette Y arm; the single-pipette module is arranged on the single-pipette Y arm and slides along the single-pipette Y arm. The invention provides the nucleic acid extractor which is simple in structure, capable of preventing cross contamination and small in difference.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a nucleic acid extraction instrument. Background technique [0002] Nucleic acid is a biological macromolecular compound synthesized by many nucleotides, and is one of the most basic substances of life. Nucleic acid widely exists in all animal and plant cells and microorganisms. Nucleic acid in organisms is often combined with protein to form nucleoprotein. Different nucleic acids have different chemical compositions and nucleotide arrangement sequences. [0003] Nano-magnetic beads are superparamagnetic nano-microspheres with carboxyl groups on the surface, which can be stably dispersed in water and biological buffer solutions with pH>6.5 (such as phosphate, Tris, carbonate, borate and other buffers) . Its surface is rich in carboxyl groups, which can be covalently combined with biological ligands, and because of its superparamagnetism, it can be quickly separate...

AI Technical Summary

Problems solved by technology

However, it is quite difficult to purify samples manually. Not only does it need to choose a suitable purification technology, but also the workload is particularly large and the repeatability is poor.

It is difficult to meet the current rapid development of extraction and purification of high-throughput samples

At present, most inspection institutions adopt the method of manual experimental operation and semi-automatic extraction device. The extraction device only has a single function of magnetic bead movement, and the pretreatment of samples and reagents and the separation of extracted products are all done manually by the operator.

There are individual differences in manual operation, which not only affects the accuracy of the results, but also limits the throughput of the test when the number of samples is large
